  • 48 GB capacity scales memory-intensive workloads on supported Supermicro servers
  • Registered ECC design corrects single-bit errors to protect data integrity under full load
  • DDR5 4800 CL40 timing matches the motherboard's memory controller specification exactly
  • 1 V operating voltage reduces power draw per module in dense configurations
  • 288-pin RDIMM form factor fits the required slot type for verified compatibility

Exact-match server upgrade

This 48GB DDR5-4800 RDIMM delivers the precise 2Rx8 registered ECC configuration that the Supermicro H14DSH memory controller expects. It operates at 1.1V with CL40 timing so the module is recognised at full capacity and runs at its rated speed without manual tuning.

Build integration

The 288-pin registered form factor is the only type the H14DSH accepts; UDIMM or SODIMM modules will not fit or function. Registered architecture offloads the memory controller, allowing every supported slot to be fully populated while ECC corrects single-bit errors before they reach production workloads.

Thermals and power

Bare modules without a heat spreader rely on chassis airflow directed across the DIMM slots, a standard design in 1U and 2U server enclosures. At 1.1V the kit draws minimal power per module, keeping thermal load low even when all channels are populated at the rated 4800 MT/s.

Questions about this item

Will the 1.1V operating voltage of this DDR5 RDIMM stay stable under sustained server workloads?

The module is rated for 1.1V and uses registered ECC architecture, which buffers the signal to the memory controller and helps maintain stability when all slots are populated.

How much heat does this 48GB DDR5 4800 CL40 module generate during continuous operation?

It has no heat spreader and runs at the standard 1.1V for DDR5, so thermal output is typical for a registered DIMM at this speed and density.

Does my Supermicro H14DSH motherboard need a specific BIOS version or CPU to recognise this 2Rx8 registered ECC memory?

The module is verified for the Supermicro H14DSH; consult the board manual for supported capacities, population order and any required firmware updates.
